在MATLAB中,可以使用find函数来查找数组中跟随特定值的元素。find函数的语法如下: 代码语言:matlab 复制 indices = find(array == value) 其中,array是待查找的数组,value是要查找的特定值。find函数会返回一个包含满足条件的元素索引的向量。 下面是一个完整的例子: 代码语言:matlab 复制 % 创建一个数组 ...
In MATLAB I have a very large matrix (matrix A). Now I would like to find the row-index of the row which contain certain values in thesecondcolumn. These values - which I'm looking for in Matrix A - are stored in anonther Matrix (Matrix B) with consists out of a row (800 ...
ind = find(strcmp(names,'Charlie')); % strcmp接受向量的输入 返回Logical数组 % find紧接着找出逻辑数组中非零元素的Index numbers{ind} 其中第3行strcmp接受元胞作为输入,在其中寻找Charlie,find函数将返回Charlie所在的位置,这样的方式比使用for循环要快,但无一例外的是,两种方法都要从头开始遍历一个数组,终...
Define a vector with a repeated value. A = [9 2 9 5]; Find the unique values ofAand the index vectorsiaandic, such thatC = A(ia)andA = C(ic). [C, ia, ic] = unique(A) C =1×32 5 9 ia =3×12 4 1 ic =4×13 1 3 2 ...
To find a specific integer value, use the==operator. For instance, find the element equal to13in a 1-by-10 vector of odd integers. x = 1:2:20 x =1×101 3 5 7 9 11 13 15 17 19 k = find(x==13) k = 7 To find a noninteger value, use a tolerance value based on your ...
% extensions, use the IMFORMATS function. If IMREAD cannot find a file % named FILENAME, it looks for a file named FILENAME.FMT. % % The return value A is an array containing the image data. If the file % contains a grayscale image, A is an M-by-N array. If the file contains...
如果仅仅对比matplotlib来讲,MATLAB不仅强在绘图速度,绘图交互性,更主要的是matplotlib是伪3D绘图,而...
雷达信号处理波达方向估计(direction of arrival, DOA)的内容足够写一本书了,如 《阵列信号处理及MATLAB实现》、《空间谱估计理论与算法》这两本都是很好的参考。 不过具体到可以应用到车载毫米波雷达的DOA估计算法却不多,因为车载毫米波雷达会随着车一起运动,这就将那些需要多快拍才能实现测角的算法排除在外。此外...
Consider using argwhere in Python to replace MATLAB's find function. For example, import numpy as np A = [1, 2, 3, 9, 6, 4, 3, 10] np.argwhere(np.asarray(A)>=9)[0][0] # Return first index returns 3. Share Improve this answer Follow edited Aug 4, 2016 at 22:37 answ...
